fix: Docker build errors — Prisma generate order, .dockerignore multi-service

- Dockerfile: move prisma generate BEFORE nest build (fixes TS2305 PropertyType)
- .dockerignore: remove apps/web + libs/ai-services exclusions (needed by Kaniko)
- CI: add pnpm db:generate step before lint/typecheck/build
